  • Publication number: 20140223932
    Abstract: An apparatus harvests latent energy and water by adiabatically decompressing a controlled volume of atmospheric air to lower its pressure and temperature below the saturation point of included water vapor, thus causing the water vapor to change state to nonvaporous water and release to the decompressed air thermal energy associated with the change of state. The apparatus then extracts the nonvaporous water, leaving the released thermal energy in the decompressed air. The apparatus then recompresses the decompressed air, which will have a resulting temperature, and thus a thermal energy, greater than those of the initially ingested air, and harvests the recompressed air and its increased thermal energy. The apparatus can also humidify and warm atmospheric air before it is ingested to increase appreciably the amount of harvested thermal energy.

Along an air flow path (510) through the case, a refrigerant-to-air heat exchanger (60) has an evaporator section (112) and a reheat section (114). A preconditioning section (110) may be upstream of the evaporator section (112) and the evaporator section is upstream of the reheat section (114). Along a refrigerant flow path (520), the reheat section (114) is downstream of the preconditioning section (110) (if any) and upstream of the evaporator section (112) and an expansion device (62) is between the reheat (114) and evaporator (112) sections.

  • Publication number: 20140165633
    Abstract: An air compressor system is disclosed that includes a housing sized to enclose an air compressor pump as well as a dryer structured to remove moisture from air that is compressed by the compressor pump. The air compressor pump may be intermittently placed into operation, but the dryer itself is structured in one form to continuously maintain a heat exchanger in a desired temperature range in anticipation of operation of the air compressor pump. The heat exchanger of the dryer can include sufficient thermal mass such that a refrigerant pump of the dryer need not be operated continuously in anticipation of operation of the air compressor pump. While a cooling air flow can be created by operation of the air compressor pump, when the air compressor pump is not operated a cooling fan can be used provide cooling to the heat generating components of the dryer.

  • Patent number: 8753566
    Abstract: The invention relates to methods and apparatuses for treating a condensate stream from a condenser that contains odorous compounds, such as various condensate streams produced in a rendering process. In one embodiment, the condensate stream is treated by adding an oxidizer to the liquid condensate stream to oxidize odor-causing compounds in the stream prior to being treated in a waste water pre-treatment system. In this manner, the odor resulting from these compounds can be reduced or eliminated.

  • Publication number: 20140096548
    Abstract: A device that collects water vapor, from the ambient air, through condensation or deposition, on the surface of its unique heat exchangers, which are embodied with opposing intertwined and alternating refrigeration circuits. In a dual refrigeration circuit/dual heat exchanger configuration, one refrigeration circuit is responsible for freezing heat exchanger A and heating heat exchanger B while the other refrigeration circuit is responsible for heating heat exchanger A and freezing heat exchanger B. The alternating refrigeration circuits work together to intermittently freeze then thaw each heat exchanger. The water run-off from the thawing process is then collected for use. The condenser tubes of one refrigeration circuit are positioned proximate to the evaporator tubes of the second refrigeration circuit to facilitate the exchange of heat. The system may further comprise heat exchanger fins in contact with the tubes. Multiple pairs of heat exchangers may be utilized.

  • Patent number: 8689571
    Abstract: Provided is a dryer for minimizing moisture entrained within a refrigerant used to provide a cooling effect to a temperature-controlled environment, and a refrigeration appliance including such a dryer. The dryer includes a housing defining a drying chamber and a desiccant disposed within the drying chamber for removing at least a portion of the moisture from the refrigerant. A first outlet is formed in the housing adjacent a lower region of the drying chamber when the drying chamber is viewed in an operational orientation. A second outlet is also formed in the housing at an elevation vertically above the first outlet when the dryer is viewed in the operational orientation for discharging at least a portion of the refrigerant introduced into the drying chamber to be delivered to a second heat exchanger with a relatively-low internal pressure. The elevation of the second outlet relative to the first outlet promotes the discharge of the refrigerant through the first outlet instead of through the second outlet.

  • Publication number: 20140083120
    Abstract: The present invention describes an atmospheric potable water generator apparatus and method of use powered entirely by renewable energy sources, which generates water from atmospheric air. The apparatus uses solar energy to heat atmospheric air in a condensing air chamber, uses wind to cool the air, condenses water on a cooling surface thereby creating potable water from atmospheric air. The apparatus may be used off the energy grid and can be applied on a large scale or for personal portable use.

  • Publication number: 20140075977
    Abstract: An air conditioning system comprises a housing defining a first airflow path therein between an outside air inlet over a cooling coil and an outlet for delivering outside air from said outside air inlet over said coil to the outlet, a second airflow path between a return air inlet over the cooling coil and to the outlet for delivering return air over the cooling coil, and a third airflow path between the return air inlet and the outlet for delivering return air through the housing without passing over the cooling coil. The system includes outside, return, and bypass air dampers that are sequentially moveable between open and closed positions for directing air through or preventing air from entering the first, second, and third airflow paths, respectively. A controller independently controls the opening and closing of each damper in response to data received from the sensor.

  • Publication number: 20130319021
    Abstract: A system and method recover water from an ambient airstream. Dehumidification of the airstream is also achieved by removal of the water. A device of the system includes a chamber having a group of trays that hold respective amounts of liquid desiccant in each tray. A foam media absorbs the desiccant to increase an exposed surface of the desiccant to the airstream. Fans and valves are used to dynamically control airflow through the device. A charge cycle circulates air through the device to remove water vapor from the airstream. A subsequent extraction cycle removes water collected in the liquid desiccant by a condenser communicating with the chamber. An integral heat exchanger adds heat to the chamber during the extraction cycle. A controller is used to integrate and manage all system functions and input variables to achieve a high efficiency of operational energy use for water collection.
